Overview[ edit ] In the scientific method , an experiment is an empirical procedure that arbitrates competing models or hypotheses. However, an experiment may also aim to answer a “what-if” question, without a specific expectation about what the experiment reveals, or to confirm prior results. If an experiment is carefully conducted, the results usually either support or disprove the hypothesis.

Sea-Floor Spreading Lab INTRODUCTION In the late s, considerable research was conducted to find a means of detecting large steel objects beneath the ocean surface (submarines). As a result, sensitive equipment was constructed that could detect very small changes in the earth’s magnetic field – and could be carried in.

We review the methods and applications of photo-based 3D reconstruction techniques. Abstract This contribution reviews the use of modern 3D photo-based surface reconstruction techniques for high fidelity surveys of trenches, rock exposures and hand specimens to highlight their potential for paleoseismology and structural geology. We outline the general approach to data acquisition and processing using ground-based photographs acquired from standard DSLR cameras, and illustrate the use of similar processing approaches on imagery from Unmanned Aerial Vehicles UAVs.

It is shown that digital map and trench data can be acquired at ultra-high resolution and in much shorter time intervals than would be normally achievable through conventional grid mapping. The resulting point clouds and textured models are inherently multidimensional x, y, z, point orientation, colour, texture , archival and easily transformed into orthorectified photomosaics or digital elevation models DEMs.

We provide some examples for the use of such techniques in structural geology and paleoseismology while pointing the interested reader to free and commercial software packages for data processing, visualization and 3D interpretation. Photogrammetric models serve to act as an ideal electronic repository for critical outcrops and observations, similar to the electronic lab book approach employed in the biosciences.

This paper also highlights future possibilities for rapid semi-automatic to automatic interpretation of the data and advances in technology.

The Boise State University Isotope Geology Laboratory (IGL) is a state-of-the-art facility for the analysis of radiogenic isotopes in Earth materials, with a focus on in situ and high-precision geochronology (U-Pb zircon) and tracer isotope geochemistry. These tools can be applied to a variety of problems in igneous and metamorphic petrology.

Chamberlain used newly developed mineral-dating techniques he created to determine the age of volcanism on Mars at million years ago, as well as the timing of a large-impact event 22 million years ago that launched rocks off the surface of Mars. A University of Wyoming research professor has helped solve the question of how old Mars meteorites are and when volcanism actually occurred on the red planet. The rocks eventually fell to Earth as meteorites. The dating technique required the use of a specialized instrument called a secondary ionization mass spectrometer or SIMS, of which only three exist in North America, Chamberlain says.

The instrument analyzes a mineral sample by excavating microscopic pits about 1 micron deep by 20 microns in diameter in the rock sample and analyzing the isotopic compositions of the excavated material. For scale, the diameter of a human hair is roughly microns, Chamberlain says. All 18 were found within a millimeter square roughly three-fourths of an inch region of a polished surface of the meteorite.

Both minerals are major reservoirs for uranium in meteorites. The large crystals are each less than 15 microns in length, too small to separate physically from the rock. The new dating technique locates the grains using electron beam imaging instruments, and then analyzes them in-situ without needing to break the rock apart. Using the mass spectrometer, Chamberlain measured the ratio of lead to uranium, which allowed him to calculate the age of the meteorite grains.

Meteorite samples were loaned by the Royal Ontario Museum in Toronto. Mars attacks To date, 65 samples of Martian meteorites have been discovered on Earth.


But how long does it take for the organic molecules we are made of to break down after death? In general, the longer the time from death, the larger the amount of decay that should be observed. This is particularly true for soft tissue, the parts of an organism that are not mineralized such as skin, muscles, or blood vessels. In , Mary Schweitzer, then affiliated with the Museum of the Rockies, shared data suggesting the possibility of soft tissue and biomolecules preservation in a bone of Tyrannosaurus rex supposedly 68 Ma old [1].

Her findings were met with great resistance and skepticism. Similar observations of blood vessels, collagen, and osteocytes from dinosaur bone had been published by Roman Pawlicki and his colleagues since [2] , but had not stirred much debate, probably because Jurassic Park, which popularized the subject, had not been written and filmed yet.

Analyzing recent earthquakes from real data Introduction Earthquakes happen every day, a normal part of how the earth works. However, when a powerful earthquake knocks down buildings and injure people, what is normal for the earth can be shocking, devastating, and catastrophic for humans. Those who have felt the effects of a powerful earthquake are unlikely to forget the experience.

Those who have never experienced an earthquake may live in a place that will experience a significant earthquake in the future. This reminds us that human memory, and the human life span, do not provide sufficient information to assess the geological hazards of an area. To assess the seismic i.

We can calculate the half-lives of all of these elements. All the intermediate isotopes between U and Pb are highly unstable, with short half-lives. That means they don’t stay around very long, so we can take it as given that these isotopes don’t appear on Earth today except as the result of uranium decay. We can find out the normal distribution of lead isotopes by looking at a lead ore that doesn’t contain any uranium, but that formed under the same conditions and from the same source as our uranium-bearing sample.

Then any excess of Pb must be the result of the decay of U When we know how much excess Pb there is, and we know the current quantity of U , we can calculate how long the U in our sample has been decaying, and therefore how long ago the rock formed. Th and U also give rise to radioactive series — different series from that of U , containing different isotopes and ending in different isotopes of lead.

Chemists can apply similar techniques to all three, resulting in three different dates for the same rock sample. Uranium and thorium have similar chemical behavior, so all three of these isotopes frequently occur in the same ores. If all three dates agree within the margin of error, the date can be accepted as confirmed beyond a reasonable doubt. Since all three of these isotopes have substantially different half-lives, for all three to agree indicates the technique being used is sound.

But even so, radioactive-series dating could be open to question.

Its name is said to reflect a legend that states the prophet Job “Ayub” in the Quran visited this place and brought forth a spring of water by the blow of his staff on the ground. The water of this well is said to be exceptionally pure, and is regarded for its supposed “healing qualities. Ismail Samani mausoleum The Ismail Samani mausoleum 9th—10th centuries , is one of the most highly esteemed work of Central Asian architecture.

It was built in the 9th century between and as the resting-place of Ismail Samani —the founder of the Samanid dynasty , which was the last native Persian dynasty to rule the region in the 9th to 10th centuries, after the Samanids established virtual independence from the Abbasid Caliphate in Baghdad. The site is unique for its architectural style which combines both Zoroastrian and Islamic motifs.

The building’s facade is covered in intricately decorated brick work, which features circular patterns reminiscent of the sun—a common image in Zoroastrian art from the region at that time which is reminiscent of the Zoroastrian god, Ahura Mazda, who is typically represented by fire and light.
